Genes affected

LRFN5 (HGNC:20360): (leucine rich repeat and fibronectin type III domain containing 5) This gene encodes a protein that belongs to the leucine-rich repeat and fibronectin type III domain-containing family of proteins. A similar protein in mouse, a glycosylated transmembrane protein, is thought to function in presynaptic differentiation. [provided by RefSeq, Sep 2016]

The c.1384A>G (p.R462G) alteration is located in exon 3 (coding exon 1) of the LRFN5 gene. This alteration results from a A to G substitution at nucleotide position 1384, causing the arginine (R) at amino acid position 462 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
